I still remember the first time I heard this song. Played on a flute, the high, clear melody haunted me. Even in a more complicated arrangement, the melody of the song has a straight and simple quality that fits the story it tells. A baby, lying in His mother's arms in a common stable, is adored by shepherds and heralded by angels. This quiet little scene is the birth of our King, and we must "haste to bring him laud." After all, as the song promises, He has brought salvation and this day is for us to be reminded to "let loving hearts enthrone Him."
It's a beautiful message, told simply and clearly. I couldn't find a good flute version that wasn't simply an instrumental, but I like this version by Mercy Me, too.
